Operating Mode
Some products are only capable of cooling, while others can either heat or cool a space. Some products heat via "heat pump" technology while others use electric heating elements. Learn More

SEER
SEER (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER, the more energy efficient the system. Learn More

HSPF
HSPF (Heating Seasonal Performance Factor) is a measure of heating efficiency for heat pumps. It is useful for comparing energy efficiency of heat pumps. The higher the HSPF, the more efficient the system. Learn More

AFUE (%)
AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace. Learn More

Orientation
Orientation describes the direction that air will flow through a piece of equipment. (e.g. air will flow horizontally through a "Horizontal" unit heater.) Most equipment will only function properly if installed in the proper orientation.

Horizontal (19)

Upflow (18)

Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More
